Kim Clijsters was beloved by US Open fans long before she won her first women's singles title in 2005 and maybe never more-so than when she made perhaps the most endearing return to tennis in the sport's history.

After a 17-year-old Venus Williams surged into the final of the 1997 US Open before losing to Martina Hingis, the prevailing view was that she would win a Grand Slam tournament within two years.

During the four-year stretch from 2004-07, Roger Federer was at the height of his considerable powers and on the edge of invincibility. But his utter dominance ended in 2008, and, heading into New York, he was as down on himself as he had been for a very long time. That all changed at the Open, however, where the Swiss maestro rediscovered the art of his game and won his record fifth straight title.

For the first eight years of his career, Flushing Meadows bedeviled Stefan Edberg.

While Rafael Nadal was busy winning his 11th French Open title, American Alison Riske lifted a trophy of her own at the ITF event in Surbiton, Great Britain, on Sunday. The grass-court title was Riske's first at the ITF or WTA level since 2016.

As the 1975 US Open unfolded, Chris Evert was the overwhelming favorite to win the tournament, and the top seed was feared by just about all of the players in the field because defeating her on clay was such a tall task. One of the few players who could test Evert was a left-handed dynamo named Martina Navratilova.

Marco Trungelliti, the current world No. 190, has become the unlikeliest of success stories at the French Open after a last-minute, 10-hour drive from his Barcelona home to Paris led to a 6-4, 5-7, 6-4, 6-4 first-round victory over Bernard Tomic.
